We examined changes in P wave height in lead 2 of an ECG obtained during progressive exercise in 23 patients with COPD, and measured both P wave changes and pulmonary hemodynamics during exercise at a constant workload corresponding to approximately 50 to 60 percent of VO2 max in nine patients. The P wave response to exercise (delta P/delta VO2, %/ml/min), estimated by the relationship between ...
the study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. in this study, the propagation of static ...
The Gonu tropical cyclone is the strongest storm in the Arabian Sea in which has cause damage in the Iranian south coastlines. The aim of the current paper is to numerically simulate the wave’s characteristics as well as the storm surge during the Gonu event by employing the SWAN wave model and the GETM hydrodynamic model. The simulation duration is one month i.e. from15 May to 15 June 2007. Th...
A nonlinear wave transformation model which can calculate the distribution of wave height inside a harbor with good accuracy has been used to estimate harbor tranquility. In a conventional procedure, however, the characteristics of such calculation could not be applied enough because the variation of wave height ratio with the steepness of incident waves would be ignored in prediction of an occ...
The berm recession of a reshaping berm breakwater has a very important role in the stability and reshaping of this structure. In this research, the recession of the berm due to wave parameters has been studied based on 2D experimental modeling method in a wave flume. Irregular waves with JONSWAP spectrum were used. A total of 60 tests have been performed to cover the impact of wave parameters s...
